SLP Loud Mouth Exhaust w/ PowerFlo-X Crossover Pipe (2005-2006 GTO)

SLP’s 2005-’06 GTO LOUD MOUTH & LOUD MOUTH II CATALYST-BACK EXHAUST SYSTEMS provide additional horsepower and torque with an aggressive muscle car rumble. The key to both systems distinctive sound is a pair of stainless steel Loud Mouth resonators or Loud Mouth II bullet-style mufflers. The additional performance comes from the free-flow design and our built-in PowerFlo-X Crossover system that uses a power-enhancing technique from NASCAR. Both systems feature a pair of 3.5” dual wall, polished stainless steel tips. The modular design lets you convert the Loud Mouth system to a quieter Loud Mouth II system in minutes, by purchasing a pair of bolt-on Loud Mouth II bullet-style mufflers (#31063). Manufactured using 2.5” stainless steel tubing and covered by our Limited Lifetime Warranty.
